Spin on filter adapter kit converts Cummins 1969 model year and newer engines using the 256843 cartridge/canister filter to an updated spin on filter design. The kit only works with the following engine series:
N-927, NH-855, V&VT / 903, V-555 / H, Medium V, KV-12, V-12, K-6, all remote mount.
Instructions list a specific length of 5/8-18 UNF-2A bolt (length varies by engine model) which customer must supply. Kit includes all parts as shown. If your application requires the short version filter element customer will have to supply their own as we are only supplying the long filter element (equivalent to Cummins 3313287).
